WIRE-GLASS MAC INE.

of Pennsylvania, have invented a new and useful Improvement inWire-Glass Machines; and I do hereby declare the following to bea ful-l,clear, and

exact description'thereof.

My invention relates to'a' machine for making rolled .sheet-glasssuehasplate-glass, ribbed glass, prism-glass,- wire-glass, and the named canbe'made with greater expedition,- in lar er quantities per day, and atcheaper cost than with existing machines.

The invention consists,

includes a stationary roller or rollers and movable tables.

In the accompanying drawings, Figure 1 is a plan view of my improvedmachine. Fig. 2 is a side elevation of the same. Fig. 3 is a verticalsection on the line 3 3, Fig. 1. Fig. 4 j

Fig. 6-is a view taken at right-angles to Fig; 5,showing the cam for actuating thevalve; and Fig, 7 is a diagrammaticplan view of the guides for giving the straight movement to thetableswhen passing underneaththe roller.

' he present embodiment of my invention The rolleris mounted in suitablehangers 2, supported from overhead beams or frame 3. The hangers 2 areslotted, as at 4, in which slotsare shown at 1,

placed the boxes 5 for the roll-journals. The

'Oooperatin with the roller are the series of tables 7, the drawingsshowing four; but obviously'the number may be increased or di minished,as desired. These tables are mounted upon a'suitable carrier, so as tobe carried inv succession underneath the roller 1. The

its work by its own carrier shown comprises a circular rotary platform8, suitably constructed of beams and plates. This platform has a. numberof radial arms or beams 9, connected to a suitable hub 10, which isprovided with a central post 11, mounted in a stepped bearingl2. Atintervals the frame is provided with wheels 13,

which run on,.a circulartrack .14. Connected to or formedon the platformis an annular rack 15, which is engaged by a pinion 16 on adriving-shaft 17 mounted in suitable bearings and driven from anysuitable source of power, such 'as the electric motor 18. ously,however, the in any other suitab e manner. he driving mechanism includesa suitable clutch 19, by means of which the platform can be stopped andstarted at will.

The tables 7 are loosely mounted on the platform 8, butare connectedthei..bo.so as to move therewith, but so as to permit the tables toswing on the platform. Various means for connecting the t' bles to thelatform may be employed, the, drawings s' I owin a link 20, having oneend hinged to the table and its opposite end hinged to the platform.- rThe tables travel around in a circular direction with the platform; butit is. necessary when passing underneath the roller that the? move mastraight line, so that the roller wi l have a straight travel over thetable and form perfect glass.

the tables are radially .movable on the platform and connected thereto bthe link 20.- To guide the tables in a straig t line underneath theroller, said tables are provided on .their lower faces with a projectingframe 21, carrying a pair of'antifrlction-rollers 22, arranged onvertical axes. Underneath the roller 1 is a suitable stationary guide ortrack 23, whichis adapted to be, en'aged by the r0ll'ers'1'22'.

The pipes 29 are rovidedwith flexible sections 33, which alow of the lateral or radial movementof the tables 7. Each table is also provided with a whose discharge endis located inside of the track 14, the floor being provided with asuitable gutter. (Not shown.) By the pipe arrangement shown all of thetables of the series are provided with cooling-wate from a singleinlet-pipe. It is preferable o maintain the water in the tables 7 only(1 ring the period that the molten glass is bein worked. Consequentlythe pi es 29 are provided with suitable valves 35, W. .ch are soarranged as to close automatically, such as being 'rovided with s rings36, which normally ho d thevalves to teir seats. The valve-stems 37project down through stuffing-boxes and at their lower ends jcarryrollers 38, which are adapted to runovera cam-bar 39, located in properosition, so that the valve will be opened beore the table reachestheroller 1 and will'be closed after the tablehas passed the roller 1.The roller 1 likewise is hollow and has a water-inlet 40 through onejournal and an outlet 42 through the other journal, the inlet beingprovided with'a suitable cut-off valve,

. The machine so far described is adapted for making practically allkinds of rolled sheetg lass-such as plate-glass, ribbed glass,prism-glass, and the like'.' In order to make the latter, either thetable or the roller 1, or both, will be provided with suitably-shapedface to give the desired ribbing or contour to the glass. For makingwire-glass I provide means for embedding the trellis'in the glasssimultaneously with the rolling thereof. To do this, the forwarl end ofeach of the tables is provided with a clamping-bar 44 for securingtheend of the trellis 45. This clamping-bar may beoperated by any suitablemeans, such as operating-handles 47.. The trellis is carried on asuitablspool or axle 48, which is mounte ed in a-box 49,:secured to hangers 50,de-

as a gage or spacing member to hold the trelthe desired distance abovethe table 7. To keep the trellis under tension, I provide a suitabletension device, which maybe a weighted brake bearing on the spool 48 ora spring or any other suitable means, the drawings showing a spring 53,secured in the box 49 and bearing upon the roller of the trellis. Thisspring will be sufficiently stiff to keep the trellis perfectly tightduring the rolling operation. The batch of glass 54 will be poured inbetween the box 49 and the roller 1. A suitable gun 55 is provided toconfine a hatch. The sides of the table are provided with suitablestrips or bars 56, upon which the roller 1 rests, these bars determiningthe thickness of the sheet of glass. In order to make sheets of variousthicknesses, these bars are removable, as is the ordinary practice. Therear end of the table is provided with a knife 58, which will cut offthe trellis when the roller passes over the edge of said knife. Theoperation of the machine is as follows: The'tables 7 are carried aroundby the platform 8, and when they approach the roller 1 the rollers 22enter the cam-guide 24, thus swinging the tables around until theirlongitudinal axes are at right angles to the axis of the roller 1. Inthis position the platform may be stopped, glass to be poured onto thetable in front of the roller 1, or the batch of glass may be poured ontothe table .withoutstopping the platform. The table is then carried inastraight line underneath the roller 1, the latter serving to roll downthe batch of glass on the table in well-understood manner. By

the time the rear end of the table is free from the roller- 1. thecam-groove 25 will again swing the table to its normal position on theThe table will then be carried around with the carrier and can have theglass removed therefrom at any suitable point. By having a series oftables the rolling on one table may progress simultaneously with theremoval ofglass from another table, thus increasing the output of. themachine. About the time that the table is brought into position toreceive the batch of glass the spring-valve 35 will be opened by reasonof the roller 38 running ontothe cambar 39, thus admitting the coolingmedium to the table. After the table has passed from so as to permit thebatch of' -IOO underneath the roller 1 the roller 38 will run off theend of the cam-bar 39, thus permitting the valve 35 to be seated by itsspring.
